Judges 11:29-33

Then the Spirit of the LORD entered Jephthah. Jephthah passed through Gilead and Manasseh and the city of Mizpah in Gilead to the land of the Ammonites. Jephthah made a promise to the LORD, saying, “If you will hand over the Ammonites to me, I will give you as a burnt offering the first thing that comes out of my house to meet me when I return from the victory. It will be the LORD’s.” Then Jephthah went over to fight the Ammonites, and the LORD handed them over to him. In a great defeat Jephthah struck them down from the city of Aroer to the area of Minnith, and twenty cities as far as the city of Abel Keramim. So the Ammonites were defeated by the Israelites.
